So you've been meaning to waterproof your iPod but haven't gotten around to it. And now the rainy season has begun, and you're afraid of getting it wet.

Why not just watch your videos on the umbrella? That's what researchers at Tokyo's Keio University do, with their invention called the "Pileus": a system that projects photos and videos onto your open brolly. According to Plastic Bamboo, it can even stream Flickr photos and YouTube videos directly through a Wi-Fi connection.

We assume the university won't be held responsible for the sidewalk accidents that will inevitably result from people not watching where they're going.
